4.4.2Conducted Transmit Power

The conducted transmit power is another indicator that measures the performance of ME909u-521 module. The conducted transmit power refers to the maximum power that the module tested at the antenna connector can transmit. According to the 3GPP protocol, the required transmit power varies with the power class.

Table‎ 4-4lists the required ranges of the conducted transmit power of the ME909u-521 module. The tested values listed in the Test Value column must range from the minimum power to the maximum power.
